StatePosition

StatePosition[sys,crit]

gives the position in the atomic system sys of the states satisfying the state‐selection criteria crit.

Details and Options

  • An atomic system is a list of AtomicState expressions.
  • State-selection criteria are specified as for SelectStates: Boolean expressions involving the state parameters, such as StateLabel2&&F1. As a shorthand, if all states with a particular label are to be selected, just the label itself can be specified.
  • The positions are returned in the same syntax used by Position.
